2,4-Dichloro-6-phenyl-1,3,5-triazine | CAS 1700-02-3 | 98% | OLED Intermediate & Pharmaceutical Building Block

1. Product Overview
2,4-Dichloro-6-phenyl-1,3,5-triazine (CAS 1700-02-3) is a high-purity triazine derivative widely used as a key intermediate in the synthesis of OLED materials and pharmaceutical compounds. With a molecular formula of C9H5Cl2N3 and a molecular weight of 226.06 g/mol, this compound features a symmetric 1,3,5-triazine core substituted with a phenyl group and two chlorine atoms at the 2- and 4-positions.
The electron-deficient nature of the triazine ring, combined with the reactive chloro substituents, makes this compound an excellent building block for constructing complex molecular architectures through nucleophilic aromatic substitution reactions. Its well-defined crystalline structure and high batch-to-batch consistency ensure reliable performance in demanding research and industrial applications.

5. Storage and Handling

Store in a cool, dry, and well‑ventilated area away from direct light. Keep the container tightly closed in a dark place at room temperature (15–25 °C); for long‑term storage, refrigeration (2–8 °C) is acceptable but not mandatory if kept strictly dry and protected from moisture. The material is hygroscopic and moisture‑sensitive to a certain extent due to the reactive chloro groups, so avoid exposure to humid air during handling. Use in a fume hood or well‑ventilated workspace; wear appropriate PPE including nitrile gloves, safety goggles, and lab coat. Minimize dust generation; transfer with spatula in closed or semi‑closed systems. Incompatible with strong bases, strong nucleophiles (amines, alcohols) at elevated temperature, and oxidizing agents. After opening, reseal immediately and consider purging the headspace with inert gas (N₂ or Ar) if the package will be stored for extended periods. Do not store together with food, feed, or incompatible chemicals.
